Celebuzz 101 Hot Bodies: Trainer Astrid McGuire Reveals How Julianne Hough Stays Hot (EXCLUSIVE VIDEO)

Julianne Hough is hotter than ever.

Not only does she have a booming film career (in July, she stole the show from Tom Cruise in Rock of Ages, and will soon appear in Diablo Cody’s upcoming dramedy), the 24-year-old singer-dancer-actress is also one of the fittest beauties in the business.

But just how does the Dancing With the Stars champ pull it all off?

To stay in screen-worthy shape, Hough works out with top trainer Astrid McGuire.

In an exclusive video interview with Celebuzz, McGuire gave us the skinny on her workouts with Hough — who ranked No. 2 on the Celebuzz 101 Hot Bodies countdown — and how readers can get their bodies ready for the ballroom dance floor.

She also sang the praises of Hough, revealing the Footloose co-star pushes her to be a better trainer.

“She is so intense, has such drive and commitment,” McGuire said. “When she’s working out 90 minutes, I feel like I’m working out 90 minutes.”
